Rated 5 out of 5Â by Greg Great Stuff Usage Tips
In the past 6 months, I have purchased at least 2 cases of this foam. The expansive and sealing properties of this foam are incredible. I've used it to seal up drafty holes in the house, around leaky air ducts and inside new walls to keep moisture and insects on the outside. I've learned a lot about this foam and have some tricks I hope you can use.
ALWAYS shake the can well the first time. The foam really does tend to settle in the can and needs to be remixed for best consistency.
Make sure the trigger is tightly secured. I even check it from time to time as I use it.
Be light on the trigger, especially the first time. There is a lot of pressure in that can and it the foam will escape faster than you'd probably like it too if you squeeze too hard.
Try not to let the foam weigh itself down. It will start to drip and fall if you get too much in one section. That's when things get messy. If you have to, wait for it to start setting up a bit and then spray some more to fill in the remaining gaps.
Get the nozzle as deep into the crack as you can. That way the foam really fills up the void from the inside out.
Once dry, the foam can be cut easily with a sharp knife or razor blade. I have used it as a backing for caulk or even putty before and then sanded and painted over it.
If you don't use the whole can, clean out the nozzle and store it. It can be re-used later.

Rated 4 out of 5Â by paul185 Great product, but...
This gap and crack foam sealant is great! It really does work and seals well from drafts and moisture. I've used it in my basement and outside shed. It's tricky to apply at first, but once you get used to how much comes out and how to apply it it's much easier. Fyi, it does expand about x5 as much as you squeeze out so be aware! They only downside to this product is that it's a single use design. If you've only used half a can, you can't save the rest for another time as the foam expands in the tube and blocks it. But for a one-time projects it's great!

Think out of the can. I have used this to insulate cold spots in walls where the insulation settled. I drill holes thru the plaster 6-8" apart and squirt foam in til the tone changes. Have plenty of holes drilled and you will never have a partial can. After it is cured use something pointy like a potato peeler to remove excess at hole, fill with spackle lite and touch up paint. I insulated a very cold bathroom that was a porch in a previous life this way.

Good stuff. I used it a few times since I've had it and it worked like promised.

Rated 2 out of 5Â by Tim123 Must Use Whole Can First Time - WASTES PRODUCT
The cured product is great stuff. The application and management of the product is POOR. You must use the whole can the first time...you CANNOT REUSE A PARTIALLY USED CAN. So, how many times are you going to need exactly one can of product??? Even with first use, when you get down to about 25% of product left, it crawls slowly out of the can. Until they can fix the application problems, or they lower the price 25% I would not buy it.
